12. Care

After each use, remove any pieces of thread, material, and fluff. Only in this way will you ensure that the sewing machine continues to work correctly and lasts for a long time.

_ Warning:

Make sure that the sewing machine is switched off and the plug has been pulled out of the socket to prevent accidents caused by uninten-tional switching on.

a) Clean the gripper area

_ Important!

Never disassemble the mechanical elements in the gripper area! Extensive experience with mechanical devices is required in order to reassemble these.

Only Customer Service has the special equipment necessary for disassembling the gripper mecha-nisms. If you carry out repair work yourself, the warranty will automatically be voided. It should be enough for the user just to clean this area with a brush or vacuum cleaner.

Turn the handwheel s in an anti-clockwise direction to fully raise the needle.

Then open the gripper cover “

and take out the bobbin case l.

Now remove all dirt with a brush or vacuum cleaner (with fine brush attachment).

Take the needle retainer ; off, as described in Chapter 9.

plate 2! and dismantle the stitch plate. Now remove the front cover q, if necessary, to better reach the screws. You can now clean the feeder.
